USANA’s Scientific Experts

USANA’s world-class scientists review the latest scientific literature and clinical studies on important nutrients, vitamins, minerals, and phytochemicals. They also test the potency and purity of every USANA product to ensure complete and balanced formulas. USANA scientists come from varying fields of expertise, and most have published numerous papers in their careers.

Tim Wood, Ph.D. Executive Vice President of Research and Development Dr. Tim Wood leads USANA’s scientific team and oversees research and development, quality assurance and quality control, and international regulatory affairs. He received his bachelor’s degree in environmental biology from the University of California, Santa Barbara, and a master’s degree and Ph.D. in the biological sciences from Yale University. Most recently, he received a master of business administration from Westminster College in Salt Lake City, Utah. Dr. Wood has managed research teams for nearly 20 years and brings strong organizational skills and research expertise to USANA’s product development efforts. “There are three standards that must be met before a new formulation is incorporated into any of the USANA Health Sciences product lines,” he says. “These are proven efficacy, outstanding quality, and uncompromised safety.”

John Cuomo, Ph.D. Executive Director of Research and Development Dr. John Cuomo’s experience in synthetic organic chemistry, manufacturing, and analytical methods make his contribution to USANA invaluable. He holds over 20 United States and European patents and is the author of numerous scientific papers. "There are several areas that I think set USANA apart from other nutritional companies," Dr. Cuomo says. "The first is USANA's quality assurance in product development and manufacturing. Few companies have the level of quality control that USANA does. We spend a tremendous amount of time and money making sure that product composition exactly matches what's on the label. One of the ways we do that is through our in-house testing of ingredient potency." Dr. Cuomo has seen many other companies include product lines solely based on the marketability of the products. "We won't jump on the bandwagon to join the latest health craze simply to make a profit."

Mark Brown, Ph.D. Director of Product Chemistry Dr. Mark Brown has completed extensive research in bioorganic chemistry and holds a Ph.D. in organic chemistry from the University of California and a bachelor’s degree in chemistry from California State University, Chico. With more than 15 years of chemistry experience, he is a valuable member of USANA’s scientific team.

John McDonald, Ph.D. Senior Scientist Dr. John McDonald is responsible for formulating new product concepts and is a resource for technical services and the science group. But he says his main responsibility is to be a repository of knowledge. "I'm paid to think," Dr. McDonald says. "In an age where urgency and immediate gratification are prevalent, taking the time to develop new product concepts and ideas is what I really enjoy about my association with USANA."

Brian Dixon, Ph.D. Senior Scientist Dr. Brian Dixon’s primary role is to facilitate and manage all clinical studies conducted at USANA. He earned a Ph.D. in molecular and cellular biology from Oregon State University, where he focused his research on the underlying biochemical mechanisms of the aging process and the therapeutic potential of lipoic acid. “Nutrition has always been close to my heart,” Dr. Dixon says. “I joined the USANA scientific team for their unyielding and uncompromising edict to produce the highest quality science-based health products in the industry."

Keijun Koh Product Development Manager Ms. Keijun Koh is a licensed pharmacist, who previously worked at a biochemistry laboratory as well as one of the leading trading companies in Japan, where she oversaw regulatory affairs and product development. Ms. Koh joined USANA Japan in 2003 and has since relocated to USANA’s Home Office in Salt Lake City, Utah. She currently focuses on the development of products for USANA’s Asia Pacific markets.

Todd DeBloois Food Scientist Mr. Todd DeBloois came to USANA as a food scientist with almost 10 years of experience developing food products in the food industry. A graduate from Utah State University with a bachelor of science degree in nutrition and food science, Mr. DeBloois maintains USANA’s current food products and helps in developing new products.

Jim Eng Research & Development Project Manager Mr. Jim Eng has been with USANA Health Sciences since 1996 and is currently the R&D Project Manager. He holds a bachelor of science degree in chemical engineering from New Jersey Institute of Technology and has more than 27 years of experience in the pharmaceutical and nutritional industry. As project manager, one of Mr. Eng’s primary functions is to transform research and development ideas into high-quality nutritional products.
